Sport is an activity in which emotions reach a high intensity and importance. However, there is little evidence of this relationship. In the present work, a systematic review of the research articles that relate and emotions was carried out with the objectives of describing the topics published in this line, analyzing the importance of emotions in this sport and proposing lines of research in this subject. We searched the Web of Science (WoS) database from 2008 to 2017 using the following keywords: basketball and emotion. After the systematic review of each document, 22 articles were selected that were categorized to analyze their content. Among the results, it is highlighted that the majority focused on athletes, competition and performance. More than a dozen emotional variables have been studied, with special focus on leadership or emotional state. The relative scarcity of research on the subject is confirmed. It is proposed to increase the number of researches, especially in the training categories and in coaches. Keywords: Sport; emotional state; emotional intelligence; research
